PLATING-MACHINE.

To all whom t may concern:

Be it known that I, J oHN A. L. DETERs, a subject of the Emperor of Germany, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Plating-Machines, of which the following is a specication.

This invention relates to electro-plating machines of the, type known as plating b arrels, and has for -its object a constructlon whereby the articles may be thoroughly and efficiently, plated and then automatically removed or discharged from the machine or barrel. t

With the above and other objects in view this invention consists in the construction, combination, andA arrangement vof parts all as hereinafter more fully described, claimed, and illustrated in the acompanying drawings whereinz Figure 1 is a plan view of a machine convention; Fig. 2 is a vertical section taken along the line 2 2 vof Fig. 4;l Fig. 3: is a side elevation thereof; Fig. 4 is a vertical section taken along line 4-4, F ig. 2; and Fig. 5 is a horizontal section" along line 5 5, Fig. 4, to illustrate the discharge spout.

Reference being had more particularly to the drawings, 10 designatesa tank arranged to receive the plating liquid. VAt each transverse end of the tank are suspended the zinc cuit 12.

.C In order to mount the plating barrel 13 (hereinafter described) in the tank 10, the longitudinal sides of said tank are provided, on their vupper edges, with the bearing` 14.

The plating barrel 13 is constructed polygonally and of wood, having the circular sides 15 between which are interposedv the perforated faces 16. Inasmuch as the barrel 13 is always partially submerged in the plating liquid in the tank 10,.such liquid will pass through the perforated faces 16 into the barrel, thus coming into'contact with the articles to be plated which are carried within the barrel. In order to place the articles to be plated in the barrel 13, one of the faces designated 16a is removable, the sides v15 be| ing channeled ask at 17\ to permit such removal in a horizontal plane, the face 16a being removed as illustrated in dotted lines in Fig. 2. .Eccentrics 28 are pivoted to the Specification of Letters Patent.

sides 15 and are designed to lock the mova-v ble face 16a in place.

Secured concentrically to one side 15 of bearings 14. Three pulleys 20 are mounted on the hollow shaft 18, one being provided to rotate the barrel in one direction, one to rotate the barrel in the reverse direction, and the other being merely an idler.

A hanger 21 is loosely mounted on the shaft 18, which extends into the barrel 13, on the interior -of said barrel, and has formed thereon the dependent arm 22 which carries at its terminal the wooden horizontal plate 23, said plate resting at an angle to the arm 22. Secured to this wooden plate 23 is a plate or section 24 of the metal, such as bronze, gold, silver, copper, etc., used in plating. A collar 26 held in place by a set- -screw 27 encircles the shaft 18 to retain the hanger 21 in place on said shaft. Due to its construction and mounting the hanger 21 and its arm 22 are constantly suspended bethe plating liquid, in consequencev thereof. This plate 24 of metal is in the circuit 12, one of the conductors 25 of. said circuit eX- tending through the shaft 18 and into the plating l'iquid. Manifestly, therefore, the action of the flow of current through the circuit 12, the plating liquid in the tank 10, and barrels and plate 24 will deposit the metal of said plate 24 upon the articles However the electrical connections per se are not considered novel and I make no claim for them separately.

Secured to each face 16 and obliquely across the linner side thereof is a vane or blade 29, said vanes being .providedi thoroughly to mix the plating liquid and to insure a proper contact between the articles and said liquid, at the same time aiding in the dis charge of the article from the barrel 13. A discharging blade 30 is secured to the side 15 carrying the tubular bushing 19, and is obliquely arranged with respect to said side so that articles to be discharged being directed between the side and the blade will be delivered to the bushing 19 and passed from the barrel 13. In order to aid in this discharge or delivery of the articles plated,

a vane 31 is so mounted in the bushing 19 that as said bushing rotates the articles delivered thereto by the blade 30 Will be forced by said vane 31 toward the outer end of the said bushing and there discharged.

In operation the rotation of the barrel 13 in one direction causes the vanes 29 to thoroughly mix the plating liquid'during the plating operation; While the rotation of the barrel 13 in the reverse direction Will cause the vane 29 to direct the articles Within said barrel'to' betWeen'the blade 30 and the side 15 of the barrel carrying said blade, fromwhere they Will be delivered to the interior of the bushing 19.

While the preferred form of this invention has been shown and described, it Will be understood that changes in the details of construction may be made Without depart-l ing from the scope of the invention. I clalm asmy invention:

cylinder of the barrel, one of said strips be-l ing removable to permit the introduction of the articles to be plated, andtwo end plates v .to which the strlps are secured andbetween Which they extend, one of said end plates having a large central opening through which the plated articles are ejected and the other and opposite end platel having a smaller central opening, a hollow shaft eX- vtending through said smaller central open-, ing, and means located Within the barrel for 'ejectmg the plated articles out through the larger centralopening.

2. A device of the class described comprising a tank containing plating liquid, a plating barrel rotatably mounted in the tank and adapted to contain` the articles to be plated, said barrel being perforated to permit the passage therethrough of the plating liquid, an anode of suitable plating metal arranged Within the barrel, separate electric conducting wires suitably connected to the anode and the articles to be plated, and means for ejecting the plated articles from thev barrel includlng' a tubular bushing ,in said barrel and a blade obliquely arranged Within the barrel and adapted to eject the plated articles through the opening in the bushing.

3.' A device of the class described comprising a tank containing *plating liquid, a
